Recombinant DNA is the general name for a piece of DNA that has been created by the combination of at least two strands. Recombinant DNA molecules are sometimes called chimeric DNA, because they can be made of material from two different species, like the mythical chimera.
Recombinant DNA is one of the core techniques of genetic engineering. It is the process of removing DNA from one organism and inserting it into the DNA of another organism, giving it new traits. Recombinant DNA can be used to make crops resistant to pests or disease, it can be used to make livestock leaner or larger.In medicine, the technique can be used to develop drugs, vaccines, and to reproduce important human hormones and proteins.By engineering human DNA into a host organism, that organism can be turned into a factory for important medical products. Insulin production is an excellent example of the recombinant DNA process.n medicine, the technique can be used to develop drugs, vaccines, and to reproduce important human hormones and proteins.
